In terms of physical properties, the LCD is not suitable for making curved surfaces. The OLED can be bent to any degree or even folded. Curved display currently on the market is basically fixed curvature, except that there may be distortion and discoloration of the screen. Its price is also relatively high. As a whole, curved LCD displays may be expensive for consumers to buy a transitional product, which is also a compromise in current technology development.

OLEDs are flexible, and many people think that OLED TVs will be the future star of the TV industry rather than LCD TVs or plasma TVs. However, a Japanese consortium of 13 companies and organizations has been working hard to develop an ultra-thin, flexible liquid crystal display (LCD). The company said that they have found a new way to make LCDs. They use plastic films instead of glass substrates, which will make the LCDs softer and thinner.


This is mainly because the thickness of several layers of organic thin films it requires is only 1,000 to 1,500 A degrees (0.10 to 0.15 um). The total thickness of the entire panel is less than 200um (0.2mm) after the package is filled with desiccant, which has the advantage of being light and thin.


In addition, it can be manufactured on substrates made of different materials, and a suitable flexible substrate such as plastic can be used to make the display flexible.

Let's talk about the LCD panel first. Many of my friends are aware that the LCD screens used in displays and TVs are different. The TV screens are mainly VA and IPS, and the monitor screens are mostly TN panels. The high-end products use VA panels. Both are under development. There are large differences in design parameters, and the application is not always the same.


Crystal panel


LCD TV panel brightness and contrast are relatively high, can be more rich colors, wide viewing angle range, but because of the low resolution, the pixels are coarse, the screen lines are more smooth and smooth, suitable for viewing distances beyond 1.5 meters .


LCD TV pixels thicker


The panel brightness of the liquid crystal display is generally low, the color level is not as rich as the television, the viewing angle range is narrow, the distance between the dots is small, the display image is more fine and sharp, and there is an advantage in the font representation, which is suitable for close-range viewing.


Why LCD Screen Fails to OLED


Friends who are more concerned about the electronic product industry should all be aware that LCD screens are becoming more and more "unpopular." This is not to say that LCD screens are particularly bad. On the contrary, some people are still accustomed to the flat and comfortable LCD. The unpopularity mentioned here is relative to the enterprise, because the popularity of OLED screens is far faster than our imagination. The inherent natural features of OLED make the selling points of terminal devices more colorful and diversified. LCD is now difficult to catch up with. The situation.


Early OLED screens were indeed a disadvantage. For example, the colors were too dark, the lifetime was lower than that of the LCD, and the pixel arrangement was sparse (grain sensation was obvious). However, Samsung’s largest OLED R&D base did not abandon it, and it was generally taught as a pro-son. In a few years, it was finally taught more and more. Compared with LCD screens over the past few years, they have been arrogant, seeing a lot of high-end TVs and smart phones have turned to OLED embrace, it began to realize that their accumulated technology in recent years is really weak.

The essential difference between OLED and LCD technology is actually "self-luminous" or not. Seeing the picture is very clear, the structure of OLED is simpler, and each pixel can control its own time. OLEDs are all black in dark shades, and LCD screens are still full-panel light. This is fundamentally different and forms the natural technical barrier for OLEDs and LCDs: OLEDs are thinner than your LCD! OLED is able to stretch! OLED's contrast and color gamut are higher than your LCD!
